Description
The present invention relates to the manufacture method and the equipment of transfer printing, the employed printing roller of plastic products stamp.
China's transfer printing, plastic products stamp etc. are that the eighties grows up, and are mainly used in the stamp of home decoration cloth and plastic products stamp etc.Development at present is very fast, and application is expanded day by day, has good prospects.
The transfer printing process was divided into for two steps at present basically.The first step is seal paper (print works finishes by seal paper), and the printing ink that will contain dyestuff need print on the stamp dedicated paper by flower shape.Second step was Yin Bu (factory finishes by transfer printing), this special-purpose marble paper that is printed on various colored shapes, through high temperature roll compacting (cloth and marble paper are close to pressurization), will spend shape and color to transfer on the cloth.But the general transfer printing of this transfer printing paper 2-3 time, but color and luster shoals gradually, the plastic products stamp is then more adopt be carved with decorative pattern roller directly printing forms.
In seal paper or seal plastic foil, must press the style designing requirement, first color separation divides cover engraving flower roller.This patent just relates to the artistic carving and the technology of this flower roller.
At present the engraving of printing roller mainly contains two kinds of etch and electronic engraving methods, and its engraving process is very complicated, has both comprised sensitization technology, and technologies such as metal erosion, copper facing, chromium plating are arranged again, also has many machine finishings and sand milling technology repeatedly.
More than two kinds of existing flower roller preparation method center main points be need be on metal (being generally copper) roller stock the texturing sample, as printing forme.Its major defect has following several respects:
1, operation is many, and the system roller is chronic.
2, spend roller of poor quality.Especially the most obvious with the preceding coated version of corrosion (mashed version) (being coated with the black glue of protection).During development, unexposed photoresists are by flush away, and the photoresists that exposed are stayed on the roller, form pattern thus, and this part photoresists that solidified is injury-free when making chemical attack (mashed version), need be coated with the black glue of protection thereon, and Here it is " coated version ".This operation applies with hand drawing entirely, and is not only time-consuming, and coating quality is bad, is easy to go wrong or fineness does not reach requirement.In general, the black and white film fineness of computer color splitting is goodish, but will carry out on roller by hand that corresponding to describe difficulty very big, even can't realize, so aliasing is many.Though the electronic engraving method goes a step further before than etch, during the electric knife engraving, the knife edge is blunt very easily, and carving speed is extremely slow, and still needs a series of subsequent handlings such as chromium plating, polishing, is difficult to keep flower shape original appearance.
3, environmental pollution is serious.Used photoresists are extraordinary photoresists on the roller, need to develop in the solution of preparations such as toluene, acetone, and this developing solution is poisonous.Secondly, with chemical substances such as ferric trichlorides, use dimethylbenzene when coated version when mashed version (corrosion), two kinds of system flower roller methods all need operations such as copper facing, chromium plating, and poisonous solution is more.All these with after all enter the river course, serious environment pollution.
The purpose of this invention is to provide a kind of with style computer color splitting image, text and data information without black and white film, directly output, roller is carved, make the manufacture method and the equipment of the printing roller of required decorative pattern.
The method of the laser direct engraving of printing roller of the present invention, especially the method for the laser direct engraving of transfer printing flower roller comprises following making step: (1) pre-install on computers stamp spot color separating system and style (2) on the printing roller embryo equably spraying abrasion-proof glue-line (3) the printing roller embryo is contained in (4) on the anchor clamps that are subjected to described computer control rotation can send the laser tube of etching laser beam be contained in can the high-precision servo actuator of relative laterally straight-line displacement with the printing roller embryo on; (5) described computer is coordinated laterally moving and glow frequency of the rotatablely moving of flower roller, optical system, and this three high-frequency etching laser beam on organic cooperation formation time order of moving with the vaporization of the glue-line on the printing roller predetermined point, etches the stamp style.
Described computer is coordinated laterally moving and glow frequency of flower the rotatablely moving of roller, optical system in the following way: the sensor of (1) described measurement printing roller rotating speed sends rotational speed signal to computer; (2) on the other hand, the rotary speed of stepper motor is also by grating reading device signal controlling, and the stepper motor rotation will rotatablely move to become to close and learn the horizontal rectilinear motion of planker by ball screw; (3) computer sends control signal according to rotary speed and pattern design, and the control laser tube sends the etching light beam.
The special equipment equipment of the method for printing roller laser direct engraving of the present invention comprises main motor, anchor clamps, also comprises:
Be installed in the optics planker that is subjected on the computer-controlled high-precision servo actuator, on the described optics planker laser instrument be housed;
